28 Claims.

This invention relates to lasting. machines, and more particularly to machines of the bed type provided with wiping means for wiping the marginalportion of upper materials into lasted position. The invention is herein illustrated as applied to means for lasting the toe ends of shoes-but it is to be understood that in its more general aspects it is not limited to toe-lasting means.

Bed-lasting machines having toe-embracing wipers are commonly provided with a hand lever for advancing and closing the wipers to wipe the margin of the upper inwardly over the insole and with a treadle for raising the wipers to perform what is known as the upwiping operation prior to the wiping of the margin over the insole and for later lowering them to press the upper firmly down on the insole. This affords the operator such control of the wipers as to permit them to be operated in the manner best suited to the requirements of each particular shoe. A substantial amount of force, however, is required to operate the wipers through the hand lever, especially in the latter portion of the q overwiping operation, and the force which the operator thus has to exert is, of course, greater in operating on comparatively heavy uppers than in operating on uppers made of light-weight stock. An object of the present invention, ae-

I cordingly, is to lessen the amount of Work which the operator must perform, while still affording him eifective control of the operation of the wipers. For the purposes in view, the invention, in one aspect, provides a novel organization whereby power means is used to supplement the force applied by the operator to the wipers to wipe the margin of the upper inwardly, the construction shown comprising a clutch arranged tobe actuated to connect a power-driven member to the wipers in response to resistance of the shoe to the movement of the wipers by the hand lever and under continuous control of the operator so that he may stop the power-effected movement of the wipers at any time. Preferably, as shown, i the clutch is so mounted as to partake of the movements of the wipers heightwise of the shoe and of certain adjusting movements which they may receive to position them in proper relation to different shoes, so that it may be connected to 50- the wipers in a direct manner through mechanism of simple construction operatively unaffected by such movements of the wipers. Advantageously this mechanism may, as illustrated, comprise a shaft rotatable through the clutch to ssoperate the wipers by power and also movable lengthwise, together with the clutch and a casing which supports the shaft and the clutch, to operate the wipers by the hand lever.

The above and other features of the invention, including also novel means for automatically limiting the power-effected movement of the wipers, novel means for locking the wipers in positions to which they are moved and for releasing them, and various novel details of construction and combinations of parts will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims,

The invention is herein illustrated as applied to a machine of a well-known type, various characteristic features of which are shown and described in United States Letters Patent No. 1,284,- 870, granted on November 12, 1918 upon an application of Matthias Brook, and only such parts, therefore, as it is necessary to refer to for an understanding of the invention are hereinafter mentioned. The machine is provided with a work support 2 constructed as more particularly dis closed in Letters Patent No. 1,404,188, granted on January 24, 1922 upon an application of Matthias Brock, this work support having at its upper end a spindle (not shown) arranged to enter the usual spindle hole in the heel end of the last. In the lasting operation the shoe is embraced at its heel end by a heel band 4 and is supported at its toe end on a toe rest 6. For lasting the toe end of the shoe there are provided toe-embracing wipers 8 (Fig, 2') supported as hereinafter described on a wiper head It having a cylindrical stem l2- mounted to turn in a bearing formed partly in a supporting member i4 and partly in cap plates I6 secured to this member. By turning movement of the stem I2 the wiper head I8 and the wipers may be tipped adjustably about an axis extending lengthwise of the shoe, such tipping movement being effected as heretofore by mechanism, not shown in detail, which is operated by a hand crank I8. The supporting member I4 is mounted on a rod 28 (Fig. 1) supported by upstanding lugs 22 on a plate 24 and is adjustable about the axis of this rod, which extends laterally of the shoe, by means of a hand crank 26, further to position the wipers in proper relation to the bottom of the toe end of the shoe. The plate 24 is supported on another plate 28 and is adjustable relatively to the latter about an axis (not indicated in the drawings) substantially in vertical alinement with the toe end of the shoe by means of a hand wheel 30, to position the wipers in accordance with the different contours of right and left shoes. The plate 28 is adjustable rectilinearly widthwise of the shoe relatively to a plate 32 on which it is mounted, the plate 32 being adjustable in directions lengthwise of the shoe by means of a hand wheel (not shown). The plate 32 is mounted on a support 34 having a depending portion 36 vertically movable in a guideway in the frame 38 of the machine and connected at its lower end by a link 40 to a crank arm 42 controlled by a double-acting treadle 44. By use of the treadle 44 the operator accordingly may raise the wipers to wipe the upper heightwise of the toe before they are operated to wipe the margin of the upper inwardly over the insole and may also lower them to press the upper firmly down on the insole after they have been advanced and closed more or less over the edge of the insole. The wipers are detachably secured to wiper carriers 46 (Fig. 2) which are provided with cam slots 48 arranged to cooperate with rolls 58 connected to the wiper head I 0 to determine the paths of advancing and closing movements of the wipers. The wiper carriers 46 are connected by links 52 to a crossbar 54 provided with a rod 58 longitudinally movable in a bearing in the previously mentioned stern I2 to advance and close the wipers and to retract them. Mounted over the wiper carriers on the wiper head I0 is a cover plate 58.

As thus far described, the machine herein shown is constructed substantially as heretofore. For purposes of the present invention there is secured to the left-hand end of the wiper support I4 a casting 68 having a cylindrical sleeve portion 82 (Fig. 4) the inner surface of which serves as a guideway for an enlarged head 64 formed on the left-hand end of the rod 56 and also for a hollow cylindrical member 66 which is secured to the head 64 and is provided interiorly with screw threads 68. In engagement with these screw threads are cooperating screw threads I8 formed on the right-hand end of a shaft 12 in alinement with the rod 56 and rotatably supported by ball bearings 14 and 16 in a casing 18 a cylindrical portion of which is slidingly mounted on the exterior of the sleeve 62. Splined on the shaft 12 is one member 88 of a double-acting friction clutch, and cooperating with the opposite end portions of this member are two clutch members 82 and 84 mounted to turn on the shaft 12 and held from relative separating movements by shoulders on the casing 18. Portions of the two clutch members 82 and 84 are formed as bevel-gears 86 and 88 connected together by a pinion 90 (Fig. 5) which is formed on a shaft 92 mounted on ball bearings 94 and 96 in the casing 18 at right angles to the shaft 12. Connected to the outer end of the shaft 92 is a flexible shaft 98 mounted in a flexible cable I00 and driven continuously by any suitable source of power which may be an electric motor. Mounted in an annular groove I82 in the clutch member 88 is a shoe I84 (Fig. 5) pivotally supported on a crank arm I 08 which is formed on a shaft I I18 mounted to turn in a bearing in the casing '18. It will thus be seen that when the crank arm I06 is swung in one direction the clutch member 80 is moved into clutching engagement with the member 82 and that when it is swung in the opposite direction the member 88 is moved into clutching engagement with the member 84. The members 82 and 84 are, of course, rotated respectively in opposite directions, the directions of their rotation being such that when the member 88 is in engagement with the member 84 the rod 56 is moved toward the right to advance and close the wipers by the action of the screw threads 18 on the threads 88, and when the mem ber 88 is in engagement with the member 82, the rod 56 is moved reversely toward the left to retract the wipers.

Fast on the shaft I88 is an arm III] which is connected by a link II2 to a forwardly extending hand lever Ilti pivotally mounted at its rear end on a bracket HS fast on the wiper support I4. It Will thus be seen that the clutch member 88 may be connected to the member 84 to cause the advancing and closing of the wipers by movement of the hand lever I I4 toward the right, and that by movement of this lever toward the left the member 80 may be connected to the member 82 to cause retractive movement of the wipers. The hand lever II4, however, is used not only to control the clutch, but also to operate the wipers manually by moving the casing I8 bodily along the sleeve 62, the casing being further guided in such movement by two bars H8 and I28 formed integral with or fast on the casting 6i] and extending through bearings in the casing. It will be understood that in such movement of the easing T8 the rod 58 is operated by lengthwise movement of the shaft 12 which, together with the clutch, moves with the casing. In order to render the hand lever H4 effective thus to move the casing, there is provided a pin I22 (Figs. 4 and 6) fastened at its upper end by a set screw I24 to a block I26 provided with a stem I28 mounted to turn in a lug I38 formed on the hand lever. By reason of this provision for turning movement of the block I26 the pin I22 may tip at different inclinations, but it is normally held in a substantially vertical position by two springs I32 and I34 carried by the hand lever II4, the inner ends of these springs being mounted in opposed relation to each other in recesses formed in the pin and the springs being controlled at their outer ends by screws I36 and 38 in the hand lever by means of which they may be normally compressed more or less as desired. The pin I22 extends downwardly through an opening I48 of slightly greater diameter than the pin formed in a plate I42 which is fastened to the casing 18 over an opening in the casing. Two rolls I44 and I48 supported on. a flat face I48 (Fig. 6) on the sleeve 62 are arranged respectively for wedging engagement with oppositely inclined faces I58 and I52 (Fig. 4) on the plate I42 to lock the casing 18 normally against movement in either direction and, through the casing, also to lock the wipers against inward or outward movements,these rolls being connected together by two springs I54 which tend to pull themtoward each other and thus maintain them normally in looking positions. These rolls also engage the lower end of the pin I22 and thereby hold the hand lever II4 normally in such a position that the pin I22 is spaced from the opposite sides of the opening I46 in the plate I42, as illustrated in Fig. 4. Accordingly, when the operator moves the hand lever I I4 towards the right the pin I22 acts first on the roll I46 to move the roll out of locking position and thus to release the casing 18 for movement toward the right. The pin I22 then engages the plate I42 at the right-hand side of the opening I49 and, in response to further movement of. the hand lever, acts to move the casing 18 to the right and thus to impart advancing and closing movements to the wipers. The wipers will thus be operated by the hand lever to advance and close them about the toe prior to the upwiping operation and thereafter to beginthe wiping of the upper inwardly over the edge of the insole, whereupon the increasing resistance of the upper to the movement of the wipers will cause the spring I32 to yield, so that through the link I I2 and the arm I III the clutch member 88 will be moved into engagement with the member 84, the pin I22 assuming a somewhat inclined position as the clutch is thus actuated. The wipers will therefore be further advanced and closed by powerthro-ugh the rotation of the shaft 12 in addition to the force applied thereto by the hand lever as the operator continues to pull on the hand lever suiiiciently to hold the clutch engaged. It will be understood that the clutch will be instantly disengaged to stop the movement of the wipers at any time when the operator ceases to pull on the hand lever with sufficient force to overcome the force of the spring I32, and that the wipers will be locked by the roll I44 against retractive movement from any position to which they are advanced and closed, this roll preventing any movement of the casing 18 toward the left. When it is desired to retract the wipers the operator swings the hand lever I I4 toward the left, and as the lever is thus moved the pin I22 first operates on the roll I44 to release the casing 18 for movement toward the left and then engages the plate I42 at the left-hand side of the opening I in the plate. If the shoe offers sufficient resistance at this time to retractive movement of the wipers, the lever I I4 will be moved against the resistance of thespring I34 to force the clutch member 86 into engagement with the member 82 and thus cause the wipers to be retracted at first by power, the roll I46 locking the casing 18 against any tendency of the power means to move it toward the right. This power operation, however, may not occur at the beginning of the retractive movement of the wipers, since-by use of the treadle 44 the operator will preferably raise the wipers to relieve their downward pressure on the upper before they are retracted. Accordingly, the casing 18 may first be moved toward the left to effect a portion of the retractive movement of the wipers by the hand lever, by reason of engagement of. the pin I22 with the plate I42. In order to render the power means effective thereafter to retract the Wipers through the same distance that they were previously advanced and closed by power, as is nesessary to return the parts to starting positions, movement of the casing I6 toward the left is limited by collars I56 on the ends of the bars [I8 and I20". When the movement of the casing is stopped by these collars the hand lever H4 will be further moved toward the left to connect the clutch member 80 with the member 82, so that the power means will act to retract the wipers.

The movement of the rod 56 relatively to the casing 18 to operate or to retract the wipers by power is limited automatically by stop mechanism shown best in Figs. 6 and '1. Fast on the member 66 which moves with the rod 56 is a pin I58 which extends outwardly through a longitudinal slot I60 in the sleeve 62 and through another longitudinal slot I62 (see also Figs. 1 and 3) in the casing 18, this pin being secured to the member 66 by screws I64 in engagement with flanges I65 formed on the pin. To cooperate with this pin there is provided a plate I66 mounted to turn on a stud I68 threaded in the casing 18. Adjustably mounted on this plate are two fingers I18 extending downwardly at opposite sides of the pin I58, each of these fingers being adjustable toward or from the pin along a guideway on the plate and secured in adjusted position by a screw I12. At its upper end the plate I66 is provided with a 111g I14 which lies between the inner ends of two screws I16 carried by the lever II4. Fig. '7 indicates the positions of the parts when the wipers are fully retracted, and it will be understood that when the hand lever I I4 is swung toward the right to actuate the clutch the left-hand screw I16 is carried into a position nearer the lug I14. When the wipers are operated by the power means the pin I58 travels with the member 66 toward the right, and if the operator holds the clutch engaged long enough to render the limiting means effective, the pin will engage the right-hand finger I18 and swing the plate I66 in a counterclockwise direction, so that by the action of the lug I14 on the left-hand screw I16 the lever II4 will be swung to the left to release the clutch and thereby stop the power operation of the wipers. Similarly, retractive movement of the wipers by power will be limited by the action of the pin I58 on the left-hand finger I16. By adjustment of the right-hand finger the amount of movement by power which the wipers can receive may be variably determined in accordance with the character of the work, so that the operator will not need to exercise any special care not to hold the clutch engaged too long. It will be understood that the left-hand finger, after having once been adjusted to determine the proper initial relation of the rod 56 and the casing 18, will ordinarily require no further adjustment.
